Mobile technology for obesity prevention: a randomized pilot study in racial- and ethnic-minority girls.
Trial report in American journal of preventive medicine, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 74 papers, 26 of them syntheses that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMobile technologies have wide-scale reach and disseminability, but no known studies have examined mobile technologies as a stand-alone tool to improve obesity-related behaviors of at-risk youth. PURPOSE: To test a 12-week mobile technology intervention for use and estimate effect sizes for a fully powered trial.
methodsFifty-one low-income, racial/ethnic-minority girls aged 9-14 years were randomized to a mobile technology (n=26) or control (n=25) condition. Both conditions lasted 12 weeks and targeted fruits/vegetables (FVs; Weeks 1-4); sugar-sweetened beverages (SSBs; Weeks 5-8), and screen time (Weeks 9-12). The mobile intervention prompted real-time goal setting and self-monitoring and provided tips, feedback, and positive reinforcement related to the target behaviors. Controls received the same content in a written manual but no prompting. Outcomes included device utilization and effect size estimates of FVs, SSBs, screen time, and BMI. Data were collected and analyzed in 2011-2012.
resultsMobile technology girls used the program on 63% of days and exhibited trends toward increased FVs (+0.88, p=0.08) and decreased SSBs (-0.33, p=0.09). The adjusted difference between groups of 1.0 servings of FVs (p=0.13) and 0.35 servings of SSBs (p=0.25) indicated small to moderate effects of the intervention (Cohen's d=0.44 and -0.34, respectively). No differences were observed for screen time or BMI.
conclusionsA stand-alone mobile app may produce small to moderate effects for FVs and SSBs. Given the extensive reach of mobile devices, this pilot study demonstrates the need for larger-scale testing of similar programs to address obesity-related behaviors in high-risk youth.
